Can't Activate Physx Since Update 13?

[Valkyrion]

i have GTX 780, all latest drivers for the card are installed.
run GPU-Z, PhysX is already ticked, yet warframe physx option is still greyed out.
help?

If you just have updated your drivers or you are testing different drivers, you might want to restart your computer after a driver install. 

 

This is because of Cuda. Cuda sometimes needs a reboot after a driver update.

This helped me a lot:

 

Don't update your driver. Completely remove your current driver from your computer, restart your computer, then install the latest driver.

 

Apologies for the useless advice if you already do this.

I don't know if it's the same issue for everyone, but this is the only solution that worked for me:

Go to C:\NVIDIA\DisplayDriver\GeForce337.50Driver\PhysX (or equivalent if you have a different OS or driver version), double click PhysX_9.13.1220_SystemSoftware, and select Repair. If you were still having the problem, I hope this helped!

Do you even have a Nvidia? if so, then switch PhysX in the "Nvidia Control Panel" entirely to the GPU instead of automatic.

 

If you have the newest drivers and/or the newest PhysX installed, it should work.
